Buy at RaceDayQuads ↗The Meteor75 Pro O4 is BetaFPV's cinematic 1S HD whoop, built around the standard DJI O4 Air Unit on a roomy 80.8mm frame. It targets pilots who want smooth indoor cruising and real 4K/60 onboard footage rather than racing.
BetaFPV has shipped two gyro variants - ICM42688 on early units and BMI270 on units shipped after December 25, 2025 - so verify which gyro your unit uses before flashing firmware.
Users have reported durability concerns with the DJI O4 Air Unit in crashes.
Third-party US retailers tend to list this at a substantial premium over BetaFPV's direct price.
The full story
BetaFPV stretches the Meteor75 Pro platform to an 80.8mm wheelbase with 45mm triblade props and 1102 22000KV motors to carry the O4's extra mass. The solder-free Matrix 1S 3IN1 HD combines the flight controller, a 12A (18A peak) , and a serial 2.4GHz receiver on one board (analog OSD omitted). A four-ball shock-absorbing mount isolates the O4 camera to kill jello, with a 10-35 degree adjustable camera angle in the canopy.
Factory tuning (PIDs, rates, extended throttle range) targets smooth indoor cruising and HD filming rather than racing, and the solder-free design makes setup beginner-friendly. It records real 4K/60 onboard while managing roughly 5 minutes per 550mAh pack (5:30 claimed). At 37.2g dry and 51.4g all-up it flies noticeably heavier than analog whoops, is easily pushed around by breeze outdoors, and dislikes wind.
The build uses the standard DJI O4 Air Unit (released January 2025), not the O4 Pro - a 1/2-inch sensor with no 4:3 4K modes and lower max transmit power than the Pro - and it is locked into the DJI digital ecosystem, so third-party goggles are not supported. The serial (UART/CRSF) ELRS receiver takes standard firmware updates over Wi-Fi or Betaflight passthrough. A version lets you reuse a DJI O4 unit you already own.
Pros & cons
Pros
- Records real 4K/60 (16:9) onboard footage from the DJI O4's 1/2-inch sensor - genuine HD capture from a ~51g whoop
- Dedicated shock-absorbing mount with four damping balls isolates the O4 camera, eliminating jello and image shake in HD footage
- Serial (UART/CRSF) ELRS 2.4GHz receiver, not - ELRS firmware updates over Wi-Fi or Betaflight passthrough without reflashing the FC
Show all 9 pros
- 12A continuous / 18A peak ESC and 1102 22000KV motors on 45mm triblades handle the O4's added weight with responsive thrust
- Around 5 minutes real-world flight time on a 1S 550mAh pack (5:30 claimed) - long for an HD whoop
- Camera angle adjustable from 10 to 35 degrees in the canopy
- PNP version (no air unit) lets you reuse a DJI O4 unit you already own
- Solder-free FC design and factory cinematic tune (PIDs, rates, extended throttle range) make setup beginner-friendly
- FC sustains over 3A down to 2.85V so digital video stays alive during hard voltage sag
Cons
- Heavy for a 75mm 1S whoop - 37.2g dry, 51.4g all-up with a 550mAh pack - and flight performance is not comparable to lighter analog whoops
- Easily pushed around by breeze outdoors; tuned for slow cinematic cruising, not or racing
- Uses the standard DJI O4 Air Unit, not the O4 Pro - smaller 1/2-inch sensor, no 4:3 4K modes, and lower max transmit power than the Pro
Show all 7 cons
- Locked into the DJI digital ecosystem; third-party goggles are not supported by the O4 Air Unit
- DJI O4 Air Unit durability concerns in crashes have been reported by users
- Two gyro versions in circulation (ICM42688 early units, BMI270 after Dec 25, 2025) - you must verify which you have before flashing firmware
- BT2.0 battery connector requires a compatible battery/charger ecosystem
